Hello ! First answer to Ed: your description seems to be related to logon possibilities, this area works, no problems with logging in.
Answer to Bill: ODUSER1 is not administrator. We have checked, that loading works also for a normal user. Because this is test environment, we allow loading for all programmers.
We have just done more testing, and it appears:
PUBLIC authority does not work. Not for reading documents, not for loading. Maybe with RACF this PUBLIC is not used.
So as we want to allow reading and loading, we decided to create a user group and include all users in it.
Then for this user group we give access to all folders and also allow loading.
I already thought why do we use RACF at all in test environment, as we allow so much. In production RACF is important, and we need to have a similar test environment.
